AI review costs are spiraling out of control

Uncapped models on every PR add up fast. PURA puts the ceiling back: the right model per pull request, live spend, and fine-grained budgets per team, repo, and provider.

Wasteful model usage

Routing a typo fix to a premium model burns budget on work that never needed it.

Unpredictable AI bills

With no caps, one busy sprint can send your monthly review bill skyrocketing.

Zero visibility

No idea which teams or repos drive AI cost — until the invoice lands.

Start controlling AI review in one afternoon

No rollout project, no new workflow. Engineers get fast reviews; leaders get predictable spend — right inside GitHub.

01

Install the GitHub App

Install in a couple of clicks, connect your Claude, OpenAI, or Gemini key, and pick the models you trust.

02

Set your review preferences

Tell PURA which changes need a premium review and which can go lean — in plain English. Then set daily, weekly, and monthly caps.

03

Comment /pura review

Drop /pura review on any PR. PURA sizes the change, picks the right model, and posts one clear review — summary, ranked findings, ready-to-apply fixes.

04

Stay inside the budget

Every review is tracked live against your caps. Reach a cap and PURA pauses that agent and skips the PR — so you never spend a dollar over.

Spend your best AI where it actually matters

Just write your routing rules in plain English in a .pura/PURA.md file. PURA reads each PR and your rules, then picks the right model — a top model for risky changes, a cheap one for routine work.

  • Write routing rules in plain English — no config to learn
  • Match on changed files, PR labels, repos, teams, or author
  • Top model for risky changes, cheap model for routine ones
  • Track spend by repo, team, model, and provider
.pura/PURA.md
# Just write it in plain English.

If the PR changes src/security.ts
or anything under src/payments/,
review it with gpt-5.5.

For docs, README, and dependency
bumps, use gpt-5.4-nano.

Everything else: gpt-5.4-mini.
built for engineering leaders

Govern every dollar of AI spend, down to the pull request.

The number you commit to finance is the number you'll pay — it physically cannot be exceeded, while every team keeps moving fast inside its own lane.

Org-wide ceiling

One top-line cap per agent — the number you give finance.

Per team

Give each squad its own envelope to spend.

Per repository

Cap noisy, high-traffic, or high-risk repos.

Per contributor

Stop any single author from running away.

Per pull request

A hard ceiling on what one PR can cost.

Per provider

Split spend across OpenAI, Anthropic & Google.

Every budget on daily, weekly & monthly windows.Scope each review agent by the dimension that fits — team, repo, author, or PR — and run as many agents as your org needs, so one team can't spend another's budget.

AI review without the AI chaos

Engineers get fast, focused reviews. Leaders get predictable spend, security they can approve, and keys they own.

Budgets finance actually trusts

Daily, weekly, and monthly caps per team, repo, and provider — with live spend and leaderboards in the dashboard. The bill is set before the work starts.

Your keys. No markup. Ever.

Bring your own Claude, OpenAI, or Gemini account. Inference is billed by your provider with zero markup, and keys are encrypted the moment you save them.

Security signs off in one call

We never store your code, secrets are redacted before any model sees them, and admin controls cover models, keys, and budgets.

Pricing that makes AI review easy to approve

No per-seat fees, no hidden charges. A straightforward fee based on the number of reviews.

Frequently asked questions

Everything teams ask before turning on AI code review.

How much does AI code review with PURA cost?+

PURA charges a flat platform fee per plan, metered by the number of reviews, with no per-seat fees and no hidden charges. You bring your own model API keys and pay your AI provider directly for inference — PURA never marks it up.

Does PURA work with GitHub pull requests?+

Yes. PURA is a GitHub App. Comment /pura review on any pull request and PURA posts one clear review — a summary, findings ranked by severity, and ready-to-apply fixes — right in GitHub.

Can I use my own OpenAI, Anthropic, or Google API keys?+

Yes. PURA is bring-your-own-key: connect your own OpenAI, Anthropic, or Google (Gemini) account and inference is billed directly by that provider with zero markup. Your keys are encrypted at rest and never shown again after you save them.

How does PURA keep AI code review spend under control?+

PURA distributes fine-grained budgets across every level — per agent, team, repo, provider, even per pull request — on daily, weekly, and monthly windows. When a budget is reached, PURA pauses reviews instead of overspending, so your bill stays within the numbers you set. A spend dashboard shows exactly where every dollar goes.

Which AI model does PURA use to review each pull request?+

You decide. Write routing rules in plain English in a .pura/PURA.md file so PURA sends sensitive changes (like payments or auth) to premium models and routine changes (like docs or dependency bumps) to cheaper ones.

Does PURA store my source code?+

No. Code is processed transiently to generate a review and is not retained afterward, and detected secrets are redacted before anything is sent to the model. PURA does not use your source code to train AI models.

Is AI code review a replacement for human review?+

No. PURA's reviews are advisory and assist your team. You stay in control of every merge and release decision.
